Be 1t known that I, EUGENE F. CLARK, a

citizen of the United States, residing at Leaksville, in the county ofRockingham, State of North Carolina, have invented certain new anduseful Improvements in Yarn- Spool Bearings; and I do hereby declare thefollowing to be a full, clear, and exact description ofthe inventiomsuchas will enable others skilled in the art to which it appertains to makeand use the same.

In a loom for weaving a tufted fabric, such as an Axminster carpet,spool-frames are used to carry spools upon which are` wound the dierentyarns, these frames being carried into use in the loom uponcarrying-chains.

It has been found that when one ofl the end clamps, which connects andsupports the spool-frame on the chain, becomes bent or broken to such anextent that the frame will drop from the chain, the end bearing of thespool falls away from the spool, thus permitting the spool to drop, andthereby causing great damage, and loss of time. Furthermore, to repairthe end clamp, itis necessary to remove the end bearing of the spool,thus 'causing great inconvenience, loss of time, andninjury to thepattern of the fabric. n

It is the particular object of the present invention to provide an endclamp, and an end` bearing, which are independently mounted on the tubeor quill frame or beam, with the result that should the clamp break orbend to such an extent as to cause it to leave the carrying-chain, theend bearing will remain properly engagedvwith the end spindle of thetuft spool. Furthermore, the

end clamp can be readily and easily rey moved from the tube frame,withouty dis-r turbing the end bearing.

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a front elevation of a frame showing the end clamps and endbearings, the tube beam and tuft spool being centrally broken away.

Figure 2 is an end view of the same.

Figure 8 is a vertical sectional view on the line 3-3 of Figure 2.

Figure 4 shows the end clamp and end bearing, in perspective, inwithdrawn position from the tube beam, andslightly separated from eachother.

Referring particularly to the accompanying drawing, 10 represents thetube or quillA beam,`which, as illustrated in the accompanying drawing,is a tuberectangular in cross section, and having the yarn guiding tubesor quills 11 secured to its front vertical face. The end bearings areeach represented, as a whole, bythe numeral 12, and consists vof anangle plate having the wings 13 and 14, the former of which is disposedwithin the end of the tubular beam 10, while `the latter is providedwith a bearing eye 15, on its upper end for the supporting reception ofthe pintle 16 of the end of the yarn spool 17, which spool is disposedabove and in parallelrelation to the beam 10. Formed on the lower faceof the angular plate 12, and depending therefrom in parallel relation,are the walls 18, each having the openended slot 19 in its rear verticaledge. In the wings or walls 18, forwardly of the inner ends of the slots19, there are formed the threaded openings 20, which align transverselyof the device; The walls 18, as

clearly seen in the sectional view, Figure 3,

are disposed within the end of the quill beam 10.

The end clamp includes an angle vplate 21, having ythe horizontal wing22, which is dispose'dwithin the end of the beamy 10, and beneath thewalls 18, and thefvertical wing 23, which extends upwardly against theouter face of the vertical wing 14, of the end bearing 12. The upper endof the wing 23 is offset outwardly and upwardly,as at 24, `forengagement with the carrying chain. (Not shown.) Formed in the anglexofthe plate 21, and disposed slightly inwardly from the side edges of thewings 22 and 23,

n are the vertical parallel walls 25. By spacing these walls 25 inwardlyfrom the sides of the plate 21, said walls are arranged to pass inwardlybetween the walls 18 of the plate 12, as shown in the drawing. Formed inthe walls 25, and in transverse alignment,

are the threaded openings 26., In the opposite side walls of the quillbeam 10, there are formed the threaded openings 27 and 28, forregistration, respectively, with the openings of the angle plate 12, andof the angle plate 21.` It will be noted that when the two angle platesare properly disposed in the end of the beam 10, that the slots 19 arein alignment with the openings 27, to

permit the retaining screw 29 to passftherethrough and through the walls25, whereby the end clamp will be firmly held in the beam 10. In theother openings Q8 a retaining screw 30 is engaged, to hol-d the endbearing within the beam. Should the end clamp break or bend to -asuflicient extent to permit the saine to become disengaged from thecarrying chain, vthe Vend bearing will not be disturbed, and they screw29 removed,to take out the clamp for repairs or replacement. Thus alldanger of the end of the yarn'spool falling from the frame is obviated,as the end bearing thereof will remain securely within the beam 10 bymeans of the screw 30.

Riveted, or otherwise-secured to the angle member 21, is a verticallyextendingspring arm 3l, which cooperates with the, upper end of thewi-ng23, to-,p'r'operly hold the tube frame to the chain.

It will also befnoted vthat,jby reason of the fact-that the beam 1O ishollow, there will noty be 'any tendency toward bending or warping, asis usual in beams which are generally l-fo'rin'ed from a 'solid strip ofwood. y
